I just finished installing a SprintBooster on my 2010 JK auto. Holy crap, what a difference, it works better than I expected! My biggest gripe with the JK was the lack of throttle response. The drive by wire system leaves much to be desired, but the SprintBooster solved everything I hated about driving my Jeep. If you think your JK is sluggish or unresponsive I suggest giving it a try. It won't make it any faster but the throttle will be a much more responsive to any input. The throttle feels crisp and the driving experience is completely different. Money well spent in my book, I highly recommend it to anyone who feels disappointed by the throttle response of their JK.

 

X2 Luke... been running my Sprintbooster for a week now and love the immediate pedal/throttle response It should respond like that from the factory.

 

I'll stick with my Flashpaq....

 

I'm curious how it effects gas mileage, as I have read all it really does is amplify/boost the electronic signal. If this is the same as "stomping on it" all the time, I would suspect gas mileage will take a big hit. Can anyone confirm/deny this?

If not, then yes, it would solve one of my biggest nags about the Jeep.

Dont knock it before you try it.

In all honesty I find myself driving the Jeep just as I have previously, without the SprintBooster. A person who is passenger in my Jeep wouldn't feel a difference. If you're light on the pedal I doubt you'll see a decline in gas mileage. All that this does is get rid of the delay between pedal push and engine feedback. Merging on the highway leaves me so much more confident, before I would push the gas pedal 1/2 way down and feel no response. It is truly a pleasure to drive and feels much more like my mechanically controlled throttle. Who knew a little chip could make so much difference. They should come from the factory with the "green" setting, the "red" setting is a bit to much for me. My biggest gripe was the install, yes it was easy, but you have to be a member of Cirque Du Soleil in order to contort your way under the dash and stick your arm under there to unplug the harness and plug in the SprintBooster.

 

I agree with Dave - don't knock it till you've tried it. I just installed mine last week (I have a Flashpaq too) and it's great! I run my Flashpaq on the 91 tune (can't find 93 gas around here) and liked it as an upgrade from stock, but when paired with the Sprint Booster, it was like something finally lit a fire under my Jeep! Totally different now - much better, and highly recommended.

 

Where do you purchase and what kind of money are we talking about for a better response?

Wouldn't this be the same as the superchips where you have 3 levels of throttle response in the advanced tunes option? What is the big difference between the superchips and sprint booster?


So you are saying the sprint booster is like a stackable powerchip programmer that can be combined with Superchips? What kind of gains are you seeing with them both combined?
